Letters Patent No. 97 ,803, dated December 14,1869.

IMPROVEAIENT m ORG-AN-BBLLO'WS.

The Schedule referred to in the Letters Patent and making part of thelame.

T 0 all whom it may concern.-

Be it known that I, J. R. PERRY, of Wilkesbarre, in the county ofLuzerne, and State of Pennsylvania, have invented a new and usefulImprovement in Orgain-Bellows; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, such aswill enable any person skilled in the arts to construct and use it,reference being had to the-accompanying drawings, forming part of thisspecification.

This invention relates to a new method of constructing and operatingorgan-bellows, so as to avoid the unpleasant noise usually heard, whenoperating them in the ordinary way, occasioned by the suction of theair-valves or clappers against their seats.

It also consists in the position of the same, with reference to thereed-board, keys, and also foot-boards, by which a direct motion isobtained, thereby avoiding the use of pulleys and other devices, toproduce the necessary motion on the exhaust-boards.

It consists also in saving the construction of a condrrctor orair-passage from the reeds to the receivingchamber, and avoiding theliability of splitting, by placing the bellows in a horizontal, insteadof a vertical posit-ion.

It consists also in a double receiving-chamber, from which the air isdrawn, thus avoiding the abrupt suction or force upon the reeds, ascompared to other methods.

It consists also in a device for regulating the posi tion of thesprings, which react against the exhaustboards.

Figure 1 represents an end-view, showing the positions of the boards,springs,.valves, air-chambers, exhausts, strap, and foot board; also,the device for adjusting the springs, to suit the action of thevibrating-board of bellows.

A represents a chamber on which the reed-board may be secured,air-tight.

B is an end view of the bellows-board, placed in a horizontal position,with an air-passage, O, which allows it to pass from the reeds into theair-chamber D, and

E is a stcclspring, one or more of which are used to expand thereceiving-chamber when pumping.

F is a vibrating-board, the sides and end of which are covered withgum-cloth or leather, and attached to board B, forming an air-tightchamber.

It has an air-passage, G, admitting the air into the second chamber 1,through the valve H and its smaller chamber.

The valve H is hinged or glued to the board F at K, and is operated bydrawing on the exhaustboard with the foot-board.

The passages at G and G require no valves.

At L there is an air-passage through the exhaustboards M, admitting theair into chamber N, which is formed with a valve, 0, and glued to theexhaustboards in a position so that while playing, its tendency is toremain closed, until forced open by the escaping air, which is drivenout by the reacting spring I, which spring rests on the frame Q andadjustable boards R, which are secured to horizontal board B with ascrew.

It will be seen that when the exhaust-boards are operated by the strap 8or foot-boards, as in playing, the exhaust-boards will draw out of thechamber 1, and then through valve H, a quantity of air corresponding totheir size, and the depth of stroke given; but as it is first taken fromchamber I, the effect of pressure is more uniform upon the reeds than ifdrawn directly from the. first chamber D, and as there will always be aquantity of air in chamber I, it closes valve H without any perceptiblenoise.

At the end of chamber I and valve'H, the opening formed by the piecesused in constructing the chamher is closed by apiece of gum-cloth orleather, so as to compel the air to pass through the valve H.

By hlnging the exhaust-boards to the vibratingboard F, a directconnection with the foot-board is obtained, by the straps used inworking them, and avoids the necessity of pnlleysto connect them, inobtaining the requisite movements; and by the use of the additionalchamber I, and the position of the valves H and 0, they operate withoutthe least perceptible noise. 7

The adjustable boards R of the spring-frame are to be fastened to theinside of the organmse, when their proper position is ascertained, whichis found by exhausting chamber 1), and swinging the vibrating board Fand the exhaust-board into their ex-, treme positions, which willdetermine the point to locate them, 7

Figure 2 represents a top view of chamber 1, airpassage G, (which may beholes bored 'or'a continuous slot,) valve H, and its fastening to bottomof vibrating-board F.

The opening over air-holes G must be closed.

Having thus fully described my invention,

Vhat I claim as new, and desire to secure by Letters Patent, is-

1. The additional chamber I, in combination with the chamber formed bythe suspended valve H, in the manner and for the purpose set forth.

2. The chamber N, attached tothe exhaust-boards, as arranged and for thepurpose specified.

3. Discla-iming the special arrangement of A. W. \Vilcox, patented April28th, 1868, the combination of the valve-chamber H, recess I, andchamber N, in the manner and for the purpose specified.

4. The adjustable frame It, combined with the organ-case, for thesupport of the spring P, substantially as described.
